(54) | METHOD OF MANUFACTURING BASE SHEET |
(57) A group of small pieces of divided base substrate is arrayed on a sheet without gaps
therebetween by means of a simple method. Provided is a substrate-sheet fabricating
method including a cutting step (S11) of cutting into a group of small pieces a base
substrate whose first-side surface is attached to a first sheet member; a transferring
step (S31, S32, or S33) of, after the cutting step (S11), transferring the group of
small pieces to a second sheet member by attaching the second sheet member, which
can be contracted in the direction along a surface thereof, to second-side surfaces
of the group of small pieces and by peeling off the first sheet member from the first-side
surfaces of the group of small pieces; and a contracting step (S21) of, after the
transferring step (S31, S32, or S33), making the second sheet member contract in the
direction along the surface thereof. |
